The International Classification of Diseases, Tenth Revision, Clinical Modification and Procedural Coding System (ICD-10-CM/PCS) implementation significantly decreased inpatient coding productivity by 64.5% but only 6.7% for ambulatory care. Coder training and record type impacted these results.
Area of Science:
- Health Informatics
- Medical Coding Systems
- Healthcare Administration
Background:
- The Veterans Health Administration (VHA) prepared for the October 1, 2015, transition to the International Classification of Diseases, Tenth Revision, Clinical Modification and Procedural Coding System (ICD-10-CM/PCS).
- ICD codes are critical for VHA operations, including research, performance measurement, and reimbursement.
- An ICD-10 Learning Lab was established to anticipate operational challenges during this conversion.
Purpose of the Study:
- To evaluate the impact of the ICD-10-CM/PCS conversion on coding productivity within the VHA.
- To quantify the changes in coding efficiency for both inpatient and ambulatory care settings.
Main Methods:
- Data collection was conducted across multiple VHA sites over several months.
- Standardized data collection methods were employed to ensure consistency.
- Productivity metrics were analyzed for inpatient and ambulatory care coders.
Main Results:
- A significant decrease in inpatient coding productivity was observed (64.5%).
- Ambulatory care coding productivity experienced a less substantial decrease (6.7%).
- Factors such as coder training and record type (inpatient vs. outpatient) influenced productivity.
Conclusions:
- The ICD-10-CM/PCS conversion had a more pronounced negative effect on inpatient coding productivity compared to ambulatory care.
- Coder training and the specific coding system (ICD-10-CM vs. ICD-10-PCS) are key determinants of productivity.
- Organizations should conduct site-specific analyses to understand the effects of ICD-10-CM/PCS implementation on their coding productivity.
